Spherical Roller

Spherical Roller Product Overview

GY specializes in manufacturing high-precision spherical rollers engineered to compensate for misalignment and deliver exceptional load capacity in harsh operating conditions. Our rollers are produced from bearing steel, stainless steel, stainless iron, high-carbon steel, ZOCM, and custom materials to meet the most challenging industrial requirements.

Spherical Roller Core Advantages

1. Self-Aligning Capability

• Spherical Design: The convex rolling surface matches spherical raceways, automatically compensating for 2°-3° misalignment between shafts and housings.
• Ideal For: Applications with shaft deflection, installation errors, or base deformation (e.g., long-shaft drives, heavy machinery).

2. High Load Capacity

• Radial & Axial Loads: Double-row design supports high radial loads and moderate bidirectional axial loads.
• Optimized Stress Distribution: Large contact area between rollers and raceways minimizes edge stress, enhancing resistance to shock and vibration.

3. Long Service Life & Reliability

• Material Excellence: Made from high-purity chromium steel (e.g., GCr15) with specialized heat treatment for superior hardness and fatigue resistance.
• Lubrication Efficiency: Reduced friction through optimized roller end and rib contact design, ensuring even lubricant distribution.
• Contamination Resistance: Sealed variants or reinforced cages (brass/polymer) prevent debris ingress.

4. Adaptability to Extreme Conditions

• High-Speed Operation: Advanced cage designs (steel/polyamide) minimize centrifugal effects for stable high-speed performance.
• Wide Temperature Range: Operates from -30°C to +200°C with compatible lubricants and materials.
• Harsh Environments: Coatings (zinc plating, black oxidation) enhance corrosion resistance.

5. Ease of Maintenance

• Simplified Installation: Self-aligning design reduces precision requirements during assembly.
• Separable Components: Inner/outer rings and roller assemblies can be disassembled for inspection and replacement.
